How can I get Minecraft PE on my android phone if I already bought it on my iPod?

I just switched to Google pixel phone and I wanna know if I can get Minecraft again without buying it again.

They don't carry over. If it was another iOS device, you could redownload it again for free by logging into your iTunes account again.

To get it on an android phone, you'll have to buy it again.

The operating systems are totally different, you will have to buy it again, sorry
